0601 Open Discovery Engines and Services

An open discovery engine executes open discovery services on request. Open discovery services are pluggable components that analyse data sources and document the results.

The OpenDiscoveryEngine entity creates a description of an instance of these types of engines. It is represented as a special type GovernanceEngine when it is documented in metadata.

A description of an open discovery engine is linked with a SupportedGovernanceService relationship to the description of an OpenDiscoveryService to indicate that the open discovery engine supports the open discovery service.

The OpenDiscoveryService entity describes an implementation of an open discovery service. This implementation is an specialized OCF Connector. The OpenDiscoveryService entity is a subtype of Asset and is linked with a ConnectionToAsset relationship to a Connection entity that defines how to create an instance of the open discovery service in the Egeria OMAG Server Platform.

Open discovery pipelines are specialized open discovery services that execute multiple open discovery services in a single run.

The OpenDiscoveryPipeline entity describes an open discovery pipeline. It is typically linked to a VirtualConnection with the connections of the open discovery services embedded within it.
